The genomes of chicory, endive, great burdock and yacon provide insights into Asteraceae palaeo‐polyploidization history and plant inulin production

Molecular Ecology Resources, 2022
Inulin is an important reserve polysaccharide in Asteraceae plants, and is also widely used as a sweetener, a source of dietary fibre and prebiotic. Nevertheless, a lack of genomic resources for inulin‐producing plants has hindered extensive studies on ...

Megakaryocyte and polyploidization

Experimental Hematology, 2018
In mammals, platelets are produced in the blood by cytoplasmic fragmentation of megakaryocytes (MKs). Platelet production is thus dependent on both the MK number and size. During differentiation, MKs switch from a division by mitosis to polyploidization by endomitosis to increase their size. The endomitotic process includes several successive rounds of

The ancient wave of polyploidization events in flowering plants and their facilitated adaptation to environmental stress.

Plant, Cell and Environment, 2020
Flowering plants or angiosperms consist of more than 300,000 species, far more than any other land plant lineages. The accumulated evidence indicates that multiple ancient polyploidy events occurred around 100 to 120 million years ago during the ...

Cytogenetics of Polyploids

1980
Following Winge’s classic paper on Polyploidy (1), there have been a large number of publications dealing with various aspects of the subject. However, this symposium is probably the first to bring together at one place and at one time so many different viewpoints and disciplines dealing with this subject.

Spontaneous polyploidization in cucumber

Theoretical and Applied Genetics, 2017
This is the first quantitative estimation of spontaneous polyploidy in cucumber and we detected 2.2% polyploids in a greenhouse study. We provide evidence that polyploidization is consistent with endoreduplication and is an on-going process during plant growth.

Physiology of Polyploids

1980
Polyploidy, a multiplication of the whole chromosomal complement, is a very widespread phenomenon in higher plants. Natural polyploids have been suggested to be more successful than their diploid progenitors under certain conditions. This success may be due to "balance hybridity," i.e., the combination of the advantage of hybridity together with the ...

Origins of Polyploids

1980
1. Polyploidy is a conspicuous feature of chromosomal evolution in higher plants. It is common in many genera, and numerous species are characterized by diploid and polyploid races. 2. Polyploid evolution is a process not an event. 3. Polyploid may involve somatic chromsome doubling or sexual functioning of cytologically non-reduced gametes.

DNA Damage and Polyploidization

2010
A growing body of evidence indicates that polyploidization triggers chromosomal instability and contributes to tumorigenesis. DNA damage is increasingly being recognized for its roles in promoting polyploidization. Although elegant mechanisms known as the DNA damage checkpoints are responsible for halting the cell cycle after DNA damage, agents that ...
